Subject [jira] [Created] (KARAF-6210) NoClassDefFoundError: org/apache/karaf/shell/api/action/Action when starting Karaf

Amichai Rothman created KARAF-6210:

             Summary: NoClassDefFoundError: org/apache/karaf/shell/api/action/Action when
starting Karaf
                 Key: KARAF-6210
                 URL: https://issues.apache.org/jira/browse/KARAF-6210
             Project: Karaf
          Issue Type: Bug
          Components: karaf
    Affects Versions: 4.2.4
         Environment: Stock Karaf 4.2.4 on Windows 10 with latest Oracle JDK 8.
            Reporter: Amichai Rothman

When starting karaf using equinox and some bundle in the deploy folder, many shell commands
(such as bundle:* and others) are not recognized, and the log shows NoClassDefFoundError:
org/apache/karaf/shell/api/action/Action. Some commands don't work, but others (e.g. shell:*)

This happens consistently on Windows 10, but not on Linux, not sure why.


Steps to recreate:

1. Extract stock Karaf 4.2.4.
2. In etc/config.properties change karaf.framework=felix to karaf.framework=equinox.
3. Place org.apache.aries.transaction.blueprint-2.2.0.jar (from maven) in deploy folder. This
is not the only bundle it happens with, just a public one I found for this example. From several
I tried, some recreated the issue and some did not. The bundle is not resolved due to missing
4. Start Karaf.
5. Try to run bundle:list and it'll say command not found. Or look at the karaf log and see
"java.lang.NoClassDefFoundError: org/apache/karaf/shell/api/action/Action". Use shell completion
to see that some commands are available but others are not.
